RETURN VALUES
      The strtol(), strtoll(), strtoimax() and strtoq() functions  
return the
      result of the conversion, unless the value would underflow or  
overflow.
      ***If no conversion could be performed, 0 is returned and the  
global vari-
      able errno is set to EINVAL.***  If an overflow or underflow  
occurs, errno
      is set to ERANGE and the function return value is clamped  
according to
      the following table.

Emphasis (the triple *) mine.
